Description

Technical Field

[0001] This specification relates to the technical field of port equipment, and particularly to a rope support frame for a traversing quay crane. Background Art

[0002] The rapid development of the world economy has driven the rapid development of shipping logistics. The global container throughput has been increasing continuously, requiring ports to have higher handling efficiency. As the key handling equipment at the terminal, container quay cranes directly operate on ships and play an important role in the overall handling efficiency of the terminal. In related technologies, in order to improve the handling efficiency of quay cranes, the layout form of a quay crane with a single upper trolley has been changed to a layout form with both an upper trolley and an external trolley coexisting, that is, a traversing quay crane that "transports containers with the upper trolley and the external trolley simultaneously" is formed. Specifically, the tracks inside the two quay crane girders are for the reciprocating movement of the upper trolley, and the tracks outside the two quay crane girders are for the reciprocating movement of the inverted external trolley. This structure of the traversing quay crane greatly improves the transportation efficiency. Among them, the upper trolley needs to be lifted and moved under the traction of the upper trolley hoisting wire rope and the upper trolley traveling wire rope, and the external trolley needs to be lifted and moved under the traction of the external trolley hoisting wire rope and the external trolley traveling wire rope. All the above-mentioned wire ropes need to be supported by a rope support frame.

[0003] Currently, the rope support frame for the wire rope towing the upper trolley is that a cross beam is arranged on each of the inner tracks of the two quay crane girders, and a plurality of idler rollers are fixedly arranged on the cross beam, and the idler rollers are used to support the wire rope. However, the inventor found that the related technology at least has the following problems: For the wire rope towing the external trolley, since the external trolley is inverted on the outer tracks of the two quay crane girders, if the rope support frame for supporting the wire rope of the external trolley adopts the same fixed rope support frame structure as that of the upper trolley, it will interfere with the quay crane girder and affect the movement of the wire rope towing the external trolley; in addition, the fixed rope support frame structure adopted for the upper trolley in the prior art consumes more materials; at the same time, the idler roller structure adopted in the existing fixed rope support frame structure is simple, and the wire rope bounce phenomenon is likely to occur, affecting the stable operation of the quay crane.

[0004] Therefore, under the trend of the high-speed development of quay cranes, for the traversing quay crane, it is urgent to study a rope support frame for the traversing quay crane to support the wire rope towing the external trolley. Summary of the Invention

[0005] The embodiments of this specification provide a rope support frame for a traversing quay crane to partially solve the above problems existing in the prior art.

[0027] The following will describe in detail the rope support frame of the through-type quay crane of this specification with reference to the drawings. Without conflict, the features in the following embodiments and implementation manners may be combined with each other.

[0028] Please refer to Figures 1 to 4, an embodiment of this specification provides a rope support frame for a traversing quay crane. An external trolley girder track 5, a horizontally arranged external trolley girder top plate 6, and a vertically arranged external trolley girder vertical rod 7 are provided outside the quay crane girder 1. The bottom end of the vertically arranged external trolley girder vertical rod 7 is fixedly connected to the quay crane girder 1. The top end of the vertically arranged external trolley girder vertical rod 7 is fixedly installed with a horizontally arranged external trolley girder top plate 6, and one side of the horizontally arranged external trolley girder top plate 6 is fixedly connected to the quay crane girder 1. An external trolley girder track 5 is laid on the horizontally arranged external trolley girder top plate 6, and the external trolley 3 can move on the external trolley girder track 5; the rope support frame 4 can also reciprocate on the external trolley girder track 5. The rope support frame 4 includes a roller 41, a roller frame 42, and roller wheels 44. Among them, the roller 41 is horizontally arranged on the roller frame 42, and the roller 41 is used to support the moving external trolley hoisting wire rope 8 and the moving external trolley traveling wire rope 9. At least two rotatable roller wheels 44 are installed on one side of the roller frame 42 close to the external trolley girder track 5, and the two rotatable roller wheels 44 are both arranged on the external trolley girder track 5.

[0029] It should be noted that Figure 1 is a schematic diagram of the positions of the upper trolley 2, the external trolley 3, the quay crane girder, and the rope support frame 4. This specification has improved the simple roller structure fixedly arranged in the prior art, and designed a movable rope support frame structure to support the wire ropes for towing the external trolley. Compared with the fixed roller structure, this structure consumes less materials, is lighter in structure, and has a lower cost. Moreover, this rope support frame is specially designed for the external trolley of the traversing quay crane, and will not interfere with the quay crane girder in terms of structure, ensuring the movement of the external trolley wire ropes, ensuring the stable operation of the traversing quay crane, and having a lower investment cost.

[0030] Furthermore, a protective cover 43 is also provided on the outer periphery of the roller 41. The protective cover 43 is also arranged on the roller frame 42 and will not interfere with the movement of the external trolley hoisting wire rope 8 and the external trolley traveling wire rope 9.

[0031] It should be noted that while the protective cover 43 does not affect the movement of the external trolley hoisting wire rope 8 and the external trolley traveling wire rope 9, it avoids the phenomenon in the prior art that the wire rope bounces off the rope support frame, ensuring the stable operation of the traversing quay crane.

[0032] Optionally, a horizontally arranged anti-roller 46 is further provided below the roller frame 42. The anti-roller 46 is also arranged below the external trolley girder top plate 6, and the anti-roller 46 can move along the lower surface of the external trolley girder top plate 6.

[0033] It should be noted that the number of the anti-rollers 46 is at least two, which can ensure that the rope support 4 moves more stably along the external trolley girder track 5, improving the running stability.

[0034] Optionally, the rope support 4 further includes a side beam 11 located above the external trolley girder track 5, side rollers 45, a vertically arranged side roller connecting rod 48, and a plurality of side beam brackets 10. The plurality of side beam brackets 10 are equally spaced and arranged on the outer side of the quay crane girder 1. The side beam 11 is fixedly arranged below the side beam brackets 10, and the length of the side beam 11 extends to the side beam brackets 10 at both ends of the quay crane girder 1. That is, the side beam brackets 10 are used to better support the side beam 11. The vertically arranged side roller connecting rod 48 and the idler 41 are arranged in parallel on the idler bracket 42; in the same horizontal plane, the distance between the vertically arranged side roller connecting rod 48 and the quay crane girder 1 is less than the distance between the idler 41 and the quay crane girder 1. That is, the side roller connecting rod 48 is closer to the quay crane girder 1 than the idler 41. The top of the vertically arranged side roller connecting rod 48 is provided with a vertically arranged side roller 45, and the side roller 45 is also arranged on the side of the side beam 11 close to the quay crane girder 1, and the side roller 45 can move along the side of the side beam 11 close to the quay crane girder 1.

[0035] It should be noted that the arrangement of the side rollers 45 can further ensure the stability of the rope support 4 when moving on the external trolley girder track 5, and can ensure that the external trolley hoisting wire rope 8 and the external trolley traveling wire rope 9 are always in a lifted state.

[0036] Optionally, a plurality of side beam brackets 10 are equally spaced and arranged on the outer side of the quay crane girder 1. Specifically, the number of the side beam brackets 10 can be six, eight, ten. Of course, other numbers can also be used, and the embodiments of this specification do not limit this. When the side beam 11 is stressed, the equally spaced arrangement structure of the side beam brackets 10 can make the side beam 11 evenly stressed, extending the service life of the rope support 4.

[0037] Optionally, the side beam bracket 10 includes a horizontally arranged side beam transverse bracket 101 and a vertically arranged side beam longitudinal bracket 102. One end of the side beam transverse bracket 101 is fixedly connected to the quay crane girder 1, the other end of the side beam transverse bracket 101 is connected to the end of the side beam longitudinal bracket 102, and the end of the side beam longitudinal bracket 102 away from the side beam transverse bracket 101 is fixedly connected to the side beam 11.

[0038] Optionally, the rope supporting frame 4 further includes a traction pulley 47, which is vertically arranged on the roller supporting frame 42 between the vertically arranged side roller connecting rod 48 and the roller 41. The traction pulley 47 is used for winding a traction steel wire rope, and the traction steel wire rope is used to connect two rope supporting frames 4, so that the two rope supporting frames 4 can run stably along the external trolley girder track 5.

[0039] Optionally, when the anti-roller 46 moves along the lower surface of the external trolley girder top plate 6, the contact area between the anti-roller 46 and the lower surface of the external trolley girder top plate 6 is one-third to one-half of the length of the anti-roller 46, which improves the running stability of the through-type quay crane system.

[0040] Optionally, when the side roller 45 moves along the side of the side beam 11 close to the quay crane girder 1, the contact area between the side roller 45 and the side beam 11 is one-fifth to one-third of the length of the side roller 45, which further improves the running stability of the through-type quay crane system.

[0041] During operation, the two roller wheels 44 of the rope supporting frame 4 are pressed against the external trolley girder track 5 outside the quay crane girder 1. The roller supporting frame 42 is welded and fixed outside the quay crane girder 1, and multiple side beam brackets 10 are evenly arranged outside the quay crane girder 1. Among them, the roller supporting frame 42 and the side beam brackets 10 are both welded by steel structural parts. The anti-roller 46 of the rope supporting frame 4 is reversely clamped under the external trolley girder top plate 6, and the side roller 45 is laterally clamped on the side beam 11, where the side beam 11 is welded along the entire length of the quay crane girder 1 on the side beam bracket 10. The above structure ensures that the rope supporting frame 4 can move stably along the external trolley girder track 5, is used to carry the steel wire rope of the external trolley, and ensures the stable operation of the through-type quay crane.

Although this specification has been disclosed above with preferred embodiments, it is not intended to limit this specification. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content without departing from the technical solutions of this specification. However, as long as it does not depart from the technical content of this specification, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of this specification still fall within the scope of the technical solutions of this specification.
